Technical Specifications Matrix

Transducer System Operating Characteristics

The electrical interface generates eddy-current probe scaling metrics when paired with its matching proximity transmitter loop. Setting the physical position requires gap voltage validation (-10 VDC targets) at the terminal test points prior to monitoring active operations. This baseline signal configuration allows the proximity sensor to map real-time rotor dynamics under high velocity loads, while internal element insulation preserves cross-talk suppression boundaries when adjacent probe bodies are clustered on a single bearing house.

Field Assembly and Routing Protocols

Mechanical Insertion

• Thread the 8 mm probe body into the machined casing bracket bore hole, monitoring electrical voltage indicators to verify distance metrics.

• Maintain clear tracking logs to confirm the unthreaded section lines up with the mounting bracket parameters.

Cable Laying and Connection

• Route the flexible coaxial length through rigid steel conduit runs to eliminate physical shearing and protect against hot fluid exposure.

• Join the miniature male coaxial connector finger-tight to the corresponding extension interface line, avoiding over-torquing thresholds.

Technical Engineering FAQ

• What total loop power requirement does the complete monitor network command?

  The electrical interface drives operations with a supply voltage requirement from 17.5 VDC to 26 VDC at 12 mA.

• Is hot-swapping or live pulling of this coaxial probe supported?

  No, hot-swap operations are unsupported; deactivate the loop excitation source before severing or connecting coaxial paths.

• What physical length error tolerances apply to the 1.0 meter cable?

  The factory physical assembly tolerance permits variance limits of +0.25 meters and -0.10 meters.

• What thermal boundaries restrict the operation of the probe element?

  The probe tip and integrated lead cable function within a thermal boundary of -34 to +177 deg C.

• Which specific configuration option does the final 02 suffix element describe?

  The final 02 configuration suffix indicates the integration of a miniature male coaxial connector tip.

• What is the target voltage window during physical probe layout configuration?

  Engineers complete physical installation by verifying gap voltage validation (-10 VDC targets) inside the linear zone.

• Does this specific 7200 series part number include stainless steel flexible armor layers?

  No, this specific suffix string indicates a standard bare coaxial jacket configuration without external armor.

• What are the physical weight and outer dimensions for structural manifest records?

  The net element mass is 0.12 kg, packed inside physical spatial constraints measuring 1.2 x 1 x 60 cm.
